Cyanobacteria, or blue-green algae, can be used as host to produce polyhydroxyalkanoates (PHA), which are promising bioplastic raw materials. The most important material thereof is polyhydroxybutyrate (PHB), which can replace the commodity polymer polypropylene (PP) in many applications, yielding a bio-based, biodegradable alternative solution. The advantage from using cyanobacteria to make PHB over the standard fermentation processes, with sugar or other organic (waste)
materials as feedstock, is that the sustainability is better (compare first-generation biofuels with the feed vs. fuel debate), with CO2 being the only carbon source and sunlight being the sole energy source. In this review article, the state of the art of cyanobacterial PHB production and its outlook is discussed. Thirty-seven percent of
dry cell weight of PHB could be obtained in 2018, which is getting close to up to 78% of PHB dry cell weight in heterotrophic microorganisms in fermentation reactors. A good potential for cyanobacterial PHB is seen throughout the literature.

Decentralized Energy Networks based on Blockchain: Background, Overview and Concept Discussion
(2018)
This paper provides a snapshot of the globally ongoing decentralization of (business) relations in the energy sector. This tendency can be observed in other domains as well and is accompanied by new digital technological developments. Blockchain technology is assigned disruptive potential when it comes to realize those decentralization ideas. This hype about Blockchain is mainly company-driven without a solid academic basis yet. The authors are currently involved in several research efforts for utilizing distributed energy resources like photovoltaic systems, batteries and electric cars for the setup of energy communities and marketplaces. The paper, therefore, presents detailed investigations of background and motivations for decentralization and the building of (local) energy communities and (peer-to-peer) marketplaces for sustainable utilization of renewable energies. An overview of recent related Blockchain-based works is presented, and the current state and feasibility for the realization of the envisioned decentralized solutions are discussed. In this way, the work aimed at contributing to a research-based decision foundation for upcoming Blockchain-based decentralization efforts.

Industrial and institutional floor cleaning today relies on mechanical action combined with chemicals, which is costly and a burden to the environment. There are floor cleaning pads on the market which claim increased service time due to diamond particles contained in the nonwoven materials. In this study, it was investigated whether cleaning results can also be obtained with hard-particle-coated pads using only water. SiC, diamond and Al 2 O 3 were used with particle sizes between 5 and 125 µm. 5 g/m² of hard particles were applied to the pads in epoxy resin. Weight loss from abrasive cleaning in 500 cycles and gloss increase were measured. Diamond and silicon carbide particles were found to work with pure water, without the need for chemical cleaning agents.
Cloud solutions in the business are nowadays becoming more
and more popular. Many companies decide to deploy their applications
in the cloud or migrate them from their non-cloud based solutions. It
allows them to focus on functionalities and turn over the work connected
with setting up and managing an infrastructure (with its issues such as
scalability or availability) to the cloud providers.
This paper provides an in-depth analysis of cloud solutions in aspects
of distributed business services. It is supported by a web application that
is responsible for testing the provided services to supports the analysis.
Digitalisierung und Automatisierung in produzierender Industrie sind Schlagwörter heutiger Forschungsbarbeiten am Department Industrial Engineering der Fachhochschule Technikum Wien. Künstliche Intelligenz, vernetzte Sensorsysteme oder übergreifende Prozessplanung ermöglichen Optimierung hinsichtlich Produktionszeit oder Fertigung von individualisierten Produkten, was zur Losgröße 1 führt. In diesem Dokument werden Forschungstätigkeiten des Departments Industrial Engineering im Kontext Vernetzung, Servicerobotik sowie Industrierobotik zusammengefasst.
